Be it known that 1, JOHN l-lannrm BARKER, a citizen of Great Britainresiding at Beeches, Carninnnock, by Glasgow, in the county ofLilllfll'l; and State'of Scoisland, have invented a new and usefulApparatus for the Ii/laking of Belize, "films Spindles, or the like fromthe Bar Automatically on a Machine with Two, Four or Six Spindles.

The machine has an evennnmber of spindies placed horizontally one abovethe other in a fixed housing. v Each spindle has chuck to grip fingertubeto llllfi long bar, from which the bolt, nut, spindle or the likeare to be made, these a e revolving oar spinrlles;

()ppoeite each revolving spindle, in perfect alinernent is placed a toolslide or spindle with a zno'iion working to and from the revolving barspindles.

Transverse to these spindles (oar aml tool spindles) are severing slidesat the front of the machine, and forming slides at the back of themachine.

The cams and levers connected to accomthat half the number of barspincllcs constituted in a machine, are operated on only at one time, byeach set of motions.

By this arrangement the making of bolts, nut, spindles and the like aredivided into two periocls named lhe No. one period, and the No. twoperiocl.

The operation of No. one period, is the metal cumin-g of bolts, nuts,spindles Or the like, over the Whole piece, up to Where the plish thevarious motions are so arranged,

F 2 show the general arrangement and Fig.3 a diagrammatic arrangement ofa {our machine. A and A, are revolving bar spindles each carrying along; liar from which i i the like are manic. slides or spindles, tooperate on the dies A, ancl AP.

The slides and B are the tool on which tools are fixerl bars chucked inspin and C are severing" slides, and the slicles D 13 are ing slidesancl are operai-ccl by one lever E, pivoted at st, 5 the route ofmovement being from tlie cams G and on the cam place I in the drawing isThe lever ii cperatestne i; o lowesi, too slides or spinclles B, thelever a the heel operates the two highest tool sliales or scindies 3 hThe levers K and L being pivoted two extreme points, one single pair ofcame (as ward and return) operate and.

I with four bolts being made and is drawn in 'stitute the main featureof the invention.

The period No. one takes into use four working parts of the machine,which includes the tool slides or spindles B and B also the formingslides D and D The period No. two takes into use, six working parts ofthe machine which includes the severin slides C and C also the levers M,N. and. P.

All the bar spindles constituting a machine can be operated on by No.one period and No. two period.

Half the working parts of No. one period operate on half the barspindles the same time as half the working parts of N0. tWo periodoperate on the other half of the bar spindles thus, all the bar spindlesare getting full attention, half by No. one period, the other half byNo. two period.

As No. one period finishes its allotted work No. two period startsaccomplishes its allotted work then back again to the No. one period andso on alternately.

In the drawing Fig. 3 periodsat work and rest in accordance with Fig. 1and Fig. 2 but on a larger scale the tools makingan actual piece beingthe main feature.

No. one period as shown in Fig. 3 shows the tools on/ Bf spindles and Dslide, are into the metal cuttingnnd forming of the bars chuckedinspindles, notice the tools on C slide resting.

No, two period as shown in Fig. 3, shows the toolson the slide C areinto the severing of bolts made in A spindles, and as the returns thechucks are opened on the chucks are closed, thus finishes No. two

' period, notice the tools on B slides or spindles and. l) slide areresting.

I claim 7 l. Ina multiple spindle automatic mashows the two chine incombination, a frame, a series of rotatable bar spindles placedhorizontally one above the other therein, a driving means for rotatingsaid spindles simultaneously, chucking and feeding devices for each ofthe spindles, means for connecting the adjacent of said chuckino andfeeding devices in halves and means for alternately operating adjacenthalves of said devices at opposite times so that in one half the chucksopened and feeding devices operate to feed operate with the halves ofspindles and movable longitudinally in the frame transversely movableforming slides at the back of each half set of spindles, .transverselymovable severing slides at the front of each half set of spindles, saidslides provided with tools for each spindle, means for connecting toolslides forming slides and severing slides and alternately operating themin opposite directions so that While the stock in one halfof spindles isbeing operated upon the stock ir the adjacent half is being fed and thetools part time inactive, substantially as described.

3. In a multiple spindle automatic machine the combination of rotatingdrums upon which cams are fixed forward and return and that each cam inrotating comes in contact with levers attached to frame of the machineat the front and the back, the contact point of the levers arranged tostand at two extreme points of the drums circumference .allsubstantially as drawn and set forth.
